Description

Technical Field

[0001] This utility model relates to the technical field of door locks, specifically to a door leaf mortise lock body with an extremely narrow side profile. Background Technology

[0002] In modern architecture and home design, the security, durability, and aesthetics of doors are key design requirements. This is especially true in high-end commercial buildings, hotels, and upscale residences, where the demands for both functionality and appearance are increasingly stringent. Driven by these needs, various innovative door lock technologies have emerged.

[0003] A common type of door lock is the profile door leaf mortise lock body. This lock body design effectively solves the installation problems of traditional door locks on heavy or large doors. Traditional door lock bodies are relatively large and occupy a lot of space, which is not suitable for designs that require maintaining a slender door leaf appearance or compact spaces. Especially in modern architecture, more and more designs require the use of extremely narrow frame door leaves to ensure the visual effect and modern feel of the door. Therefore, there is a great demand for the research and development of narrow-frame profile door leaf mortise lock bodies. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model provides a profile door leaf mortise lock body with an extremely narrow edge, which can solve the above problems.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: A lock body for a narrow-bezel profile door leaf includes a lock body panel. A lock shell is connected to the right side of the lock body panel. A strip-shaped locking block is installed in the middle of the shell cavity of the lock shell. The locking block has a through hole one, into which a pin is inserted. A guide post is provided in the middle of the pin, and a locking block is provided at the bottom of the pin. A rounded rectangular through hole two adapted to the guide post is opened on the side of the locking block. A locking hole adapted to the locking block is opened on the lock shell. The upper end of the pin extends out of the locking block. A spring limiting piece is provided at the top of the extended end of the pin. A spring is sleeved on the extended end of the pin. One end of the spring is connected to the spring limiting piece, and the other end is connected to the locking block. A square latch is connected to the left side of the locking block. A through hole three adapted to the square latch is opened on the lock body panel. A lock cylinder is installed at the lower part of the lock shell.

[0006] Furthermore, the lower opening of the through hole is a figure-eight shaped opening.

[0007] Furthermore, the locking hole is a U-shaped hole, with the left side of the locking hole being the locking position and the right side being the unlocking position.

[0008] Furthermore, it also includes a door stop, the left side of which is provided with a snap box, the snap box having a snap-fit ​​hole adapted to the square tongue.

[0009] The advantages of this utility model are: the structure is simple and the cost is low, and it is especially suitable for door panels with extremely narrow frames. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] like Figure 1-2As shown, this utility model discloses an ultra-narrow-edge profile door leaf mortise lock body, including a lock body panel 1. A lock shell 2 is connected to the right side of the lock body panel 1. A strip-shaped locking block 4 is installed in the middle of the shell cavity of the lock shell 2. The locking block 4 has a through hole, into which a pin 10 is inserted. A guide post 11 is provided in the middle of the pin 10, and a locking block is provided at the bottom of the pin 10. A rounded rectangular through hole 2, which is adapted to the guide post 11, is opened on the side of the locking block 4. The lock housing 2 has a locking hole 12 that matches the locking block. The upper end of the pin 10 extends out of the locking block 4. A spring limiting piece 6 is provided at the top of the extended end of the pin 10. A spring 5 is sleeved on the extended end of the pin 10. One end of the spring 5 is connected to the spring limiting piece 6, and the other end is connected to the locking block 4. A square tongue 3 is connected to the left side of the locking block 4. A through hole 3 that matches the square tongue 3 is provided on the lock body panel 1. A lock cylinder 13 is installed at the lower part of the lock housing 2.

[0016] In a specific embodiment of this application, the lock housing 2 includes a lower lock housing connected to the lock body panel 1. The lower lock housing is provided with an L-shaped support positioning post and a cylindrical support connecting post. The L-shaped support positioning post is provided with a positioning protrusion for initial positioning connection with the upper lock housing. The lower lock housing is fixedly connected to the upper lock housing by screws and the support connecting post.

[0017] In a specific embodiment of this application, the upper and lower sides of the lock body panel 1 are connected to the door leaf by screws, and the lock shell 2 is installed into the preset mounting hole of the door leaf. The upper and lower sides of the door stop 8 are connected to the door frame by screws, and the latch box 9 is installed into the preset mounting hole of the door frame. The total width of the lock body panel 1 plus the lock shell 2 is 35mm. When locked, the protrusion width of the square tongue 3 is 15mm.

[0018] In one specific embodiment of this application, when unlocking, the actuating part of the lock cylinder 13 can be used to push the bolt 10 upward a short distance (overcoming the spring force), causing the locking block at the bottom of the bolt to disengage from the locking position. With continued forward actuation of the lock cylinder 13, the locking block 4 moves to the right, thereby causing the square tongue 3 to move to the right and gradually disengage from the latching hole of the latch box, until the locking block is engaged in the unlocking position under the action of the spring 5. At this point, the square tongue 3 is completely disengaged from the latching hole. When locking, the actuating part of the lock cylinder 13 can be used to push the bolt 10 upward a short distance, causing the locking block at the bottom of the bolt to disengage from the unlocking position. With continued reverse actuation of the lock cylinder 13, the locking block 4 moves to the left, thereby causing the square tongue 3 to move to the left and gradually insert into the latching hole of the latch box, until the locking block is engaged in the locking position under the action of the spring 5. At this point, the square tongue 3 is completely inserted into the latching hole.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
